4. *Review from last class*

8. Your Turn! { (x,y) | 4x- y ≥ 3 , xεR, yεR}
Graph the solution of the inequality
{ (x,y) | 4x- y ≥ 3 , xεR, yεR}

9. We can also apply this idea to word problems!

10. What inequality represents the goal?
let x = number of pairs of skis
let y = number of snowboards
100x +120y > 600
Are there any restrictions?
Since half a snow board, or a third of a pair of skis cannot be sold, the 

solution set is discrete.
xεW, yεW

11. inequality xεW, yεW restrictions 100x +120y > 600 10x + 12y = 60
x intercept
10x = 60
x = 6
(6, 0)
y intercept
12y = 60
y = 5
(0, 5)
{(x,y) Ι 100x + 120y > 600, xεW, yεW}
